“…Modified with benzo[ c ]cinnoline or its derivatives surfaces of e.g. glassy carbon [ 111 , 112 ], gold [ 113 ] or platinum [ 114 , 115 ] are often used in organic, inorganic, and biochemical catalytic transformations.…”

Azobenzene derivatives due to their photo- and electroactive properties are an important group of compounds finding applications in diverse fields. Due to the possibility of controlling the trans–cis isomerization, azo-bearing structures are ideal building blocks for development of e.g. nanomaterials, smart polymers, molecular containers, photoswitches, and sensors. Important role play also macrocyclic compounds well known for their interesting binding properties. In this article selected macrocyclic compounds bearing azo group(s) are comprehensively described. Here, the relationship between compounds’ structure and their properties (as e.g. ability to guest complexation, supramolecular structure formation, switching and motion) is reviewed.

“…All Nyquist plots were fitted as Warburg effected, diffusion controlled CPE equivalent electrical circuit. 35 As shown in Figure 3b, Charge transfer resistance (Rct) of redox couple was decreased with GC/CTP-GNR type electrodes according to bare GC electrode. The rate of redox couple electron transfer was accelerated on GC/CTP-GNR1 surface.…”

Carbonized electrode materials were prepared from carbonization of graphene nanoribbon (GNR) / coal tar pitch (CTP) composite (m% of GNR: 1%, 3%, 5% and 10%). The carbonized materials were denoted as follows: CTP-GNR1, CTP-GNR2, CTP-GNR3 and CTP-GNR4. Characterization included cyclic voltammetry (CV), infrared spectroscopy (IR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and X-ray diffraction (XRD). CTP-GNR1 was obtained as the nanocoil structure via SEM. Electrocatalytic activity for some redox probes, such as ferrocene and ferric/ferrous (K3Fe(CN)6 and K4Fe(CN)6) probe on the CTP-GNR1 modified glassy carbon (GC/CTP-GNR1) was found to be greater than others. The nanocoil material (CTP-GNR1) was used in the determination of dopamine (DA) and uric acid (UA) by differential pulse voltammetry (DPV). The electrode exhibits linear responses to DA and UA in the ranges of 2 μM–20 μM in the presence of 300 μM of L-ascorbic acid (AA). The detection limits (S/N = 3) for DA and UA are 3 nM and 6 nM, respectively.

The modification of N-phenyl-aza-15-crown-5 (PA15C5) and N-(4-aminophenyl)-aza-15-crown-5 (4APA15C5) on glassy carbon (GC) electrode was performed by the electrochemical oxidation of the corresponding azacrown derivatives in anhydrous acetonitrile media. The electrochemical behavior of the resulting modified GC electrode was investigated in the presence of electroactive redox probes and these results, together with the X-ray photoelectron spectroscopy (XPS) and reflectionabsorption infrared spectroscopy were used to confirm the attachment of these molecules onto the GC surface. The ellipsometric thicknesses of PA15C5 and 4APA15C5 films at the GC surface was obtained around 9.28±0.40 and 10.50±1.10 nm, respectively. Azacrown modified nanoscale surfaces serve as alkali metal sensor specific for their cavity in the crown ring.
